The DEWALT® 3 Piece Ergo Aviation snip set is designed with a reduced handle span, providing lower level of muscle effort required while cutting tough materials. These tools are traditionally used for cutting aluminum, vinyl siding, screening, cardboard, leather, copper and 18 to 22-Gauge sheet metal. The snip's serrated cutting edge prevent materials from slipping during use and the slip-resistant, bi-material cushion grip ensures a firm, comfortable grip.
